YOTTO C. JELINEK ATTORNEYS United States 3,437,071 BEZEL CLAMP FOR AN INDICATOR Otto C. Jelinek, Cranston, RI, assignor to Federal Products Corporation, a corporation of Rhode Island Filed Jan. 17, 1967, Ser. No. 609,376 Int. Cl. G09f 9/00 US. Cl. 116-129 4 Claims ABSTRACT OF THE DISCLOSURE An indicator casing is set into a recess in a handle unit with a lever pivoted in a recess of the handle unit so as to clamp the bezel in its rotative position of adjustment.

Background of the invention Summary of the invention A handle unit is provided with a recess to retain or receive the casing of the indicator. The adjustable or rotatable bezel of the indicator extends sufiiciently above the handle unit so as to be readily manually manipulatable to rotate it to a position to zero out the indicator hand. Extending radially from the circular bezel, there is a recess in which there is pivoted a lever which has a rotable element on one side of the pivot carried by the lever and which may be swung into a position to engage the bezel and force it diametrically so as to frictionally engage the depending portion of the bezel with the casing and hold it in position. The lever arm on the other side of the pivot is swung into the recess so that the locking lever then becomes substantially flush 'with the surface of the handle. The lever may be operated with the hand which holds the handle and indicator and without the necessity of using an additional hand, one to hold the handle and the other to turn some locking means.

Brief description of the drawings FIG. 1 is a perspective view of the handle showing in dotted lines the handle extension and a housing for a motion transmitting means;

FIG. 2 is a section on substantially line 2-2 of FIG. 1; and

FIG. 3 is a fragmental section similar to FIG. 2 but showing the clamping lever in release position.

Description of the preferred embodiment of the invention A handle unit is generally a solid construction with a recess at 11 for the reception of the casing portion 12 of an indicator having a rotatable bezel 16. This indicator carries a closure plate 13 upon which there is an annular member 14 graduated in the units which are to be measured. Beneath this annular member 14 there is a spring plate 15 which applies pressure to friction the annulus 14 between a bezel shoulder 16' and the plate 13 causing it to rotate with the bezel. A pointer 17 operates over the annulus 14 and a transparent crystal 18 is mounted in the atent 0 bezel 16 for a protection of the operating hand and the graduated annulus 14. This bezzel 16 has a depending externally ribbed flange 20 through which screws 21 extend having reduced ends 22 to enter a recess 23 in the casing 12 and retain the bezel from being lifted therefrom. However, the bezel is rotatably mounted by reason of being of a size substantially larger than the casing although retained against axial movement from the casing by the screws 21. The bezel and annulus 14, however, may be rotated so as to position its zero marking beneath the pointer when desired.

In order to lock the bezel in any position such as this zeroed position, I have provided a recess 25 in the handle unit 10 which extends generally radially from the bezel. This recess is provided with opposite flanges 26 and 27 along its sides which support a pivot pin 30 extending from one flange 26 to the other flange 27. On this pivot pin a lever designated generally 31 is pivotally mounted which is bifurcated at its ends to support a roll 32 which is pivoted in such a position that when the lever is swung from the position shown in FIG. 3 to the position shown in FIG. 2, it will engage the bezel 16 and force it in a diametrical direction from the position shown in FIG. 3 to the position shown in FIG. 2, thus clamping it firmly against the side of the casing and locking it in position. This roll 30 may be of some plastc material, such as nylon, which has some anti-friction qualities. On the other side of the pivot 30 the lever extends as at 33 providing a finger engaging portion which may be conveniently engaged to move it from the position shown in FIG. 2 to the position shown in FIG. 3 or vice versa by the same hand that grasps the handle unit or body 10, thus making it unnecessary to use two hands for the release or clamping in position of the bezel.

I claim:

1. An assembly comprising a handle unit having a recess, an indicator having a casing in said recess and a rotatable bezel on said casing, a lever extending radially outwardly of said bezel, a pin in said handle unit adjacent said recess pivotally mounting said lever, said lever having portions extending on either side of said pin, one of said portions being of a length to engage said bezel to urge it firm frictional engagement with said casing to hold it in place and the other of said portions being manually manipulatable for swinging said lever to bring said first portion into engagement with said bezel with said lever overlying said handle unit.

2. An assembly as in claim 1 wherein a second recess in said handle unit receives said lever.

3. An assembly as in claim 1 wherein a second recess in said handle unit extends radially of said first recess and casing and receives said lever.

4. An assembly as in claim 1 wherein a roll is pivotally mounted on the portion of said lever which engages said bezel.
